Classic signs and symptoms of impetigo involve red sores that quickly rupture, ooze for a few days and then form a yellowish-brown crust. The sores usually occur around the nose and mouth but can be spread to other areas of the body by fingers, clothing and towels.
A less common form of the disorder, called bullous impetigo, may feature larger blisters that occur on the trunk or diaper area of infants and young children.
A more serious form of impetigo, called ecthyma, penetrates deeper into the skin — causing painful fluid- or pus-filled sores that turn into deep ulcers.
When to see a doctor
If you suspect that you or your child has impetigo, consult your family doctor, your child's pediatrician or a dermatologist.
